NOODWORKING1VIACHINE Specification of Letters Patent.

Patented June 29, 1909.

To all 107mm it may 0012 (rm-n it known that l, llONESTUS 1d. Aliens, a citizen of the United States, residing at Nutley, in the county of Essex and State of New Jersey, have invented certain new and useful Improvements in Woodworking-Machines; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to iigures of reference marked thereon, which form a part of this specification.

This invention relates to a machine [or cutting out patterns from wood, and is adapted to give a iiine edge to the cut made in the wood and permit of the cut extending up into small corners so as to make acornplete design, and is designed to particularly take the place of hand cutting which is now necessary in wooden plaques and similar ornamental devices made of wood and supplied with a design. These plaques, as now furnished, are printed with a configuration which is treated sometimes by pyrography, but in other forms the design is cut out of tho itirst layer of veneer, of which the plaque is made up, and after this cut design is treated it is known in the trade as Flemish art. These designs, as heretofore said, have been cut out by hand, which makes them expensive and also a iinish that is not clean on ti 3 edges of the cut, and the eil'ect is also marred oy a cut running beyond the point where it should step. This machine does this cutting by a quick reciprocation ot a chisel-shaped knife, and the design can be moved along under the knife, similar to wood that is submitted to a hand saw or goods on a sewing machine. The machine also embodies an adjustable table which can be operated manually and on which the desired penetration of the wood can be adjusted, this penetration being kept uniform by the pressure supplied to the table which forces the wood against the knife or chisel.

The invention is illustrated in the accompanying drawings, in which Figure 1 a face view of the machine, and Fig. is a section of the table. Fig. 3 is a plaque showing part of it cut out, and Fig. 41 is a detail view of a veneered plaque or piece ol wood, and illustrating diagrammatically the operation of the knife of the machine on the wood.

The machine consists of a suitable base 10 forming a support [or a table 1.1 on which mounted a machine-l'rame 12 which can be oi any well known construction, and l 'iind 1 that the mechanism in a sewing machine is well adapted for the purpose, this machine being driven as usual by a belt 13, and the operation ot the machine acting to rapidly reciprocate a chisel-shaped knil'e 1st. Underneath the machine is a treadle. 15 which, when operated by the foot, acts to pull down a rod 16 which fastened at its upper end to the end of the narrow portion 17 of a plunger l8 which is adapted to slide in a cylinder ll). A spring 20 abuts on one end of the shoulder lormcd by the piston 18 and its narrow portion, and abuts on its other end on a cap 21. cap 23, on the other end ol the cylinder 19, receives the shoulder 23 of the piston 18, and acts as a stop for the upward movement ol' the piston.

The cylinder can be adjusted by rotating the nut 22 which turns on the screw-threaderl exterior ol the cylinder 19 and is locked in place by a lock-nut 24.. l prcl'er to provide the lock-nut 2 -1 with a lever 25 which projects, as in Fig. l, l'rom a slot 26 in the table 11 and provides tor the easy unlocking oi the lock-nut 2i, and then by a rotation ol' the nut 22, the cylinder it) can be moved toward and from the kuil'e ll. A tablet 27 is mounted on the end oi the plunger lb and serves to hold the work to be operated on.

in Fig. I; I show one design ol' plaque 28. Those plaques are provided with lines 2!), which lines are allorward used in ornameutiug the plaque, or any other piece ol' wood-work, by pyrography, or in this process by cutting away the design on the lines 2%) and uncovering the portions Si) olone ol the lower veneers, those veneers 3i being assembled, as shown in Fig. l, to make up the plaque. When it is desired to use the machine, the loot lever 15 is operated, alter the height oi the table has been adjusted by means ol' the nut 22, and the machine being in operation, the plaque is placed with one ol its lines to be cut out umlerneath the knitc lei which is rapidly reciprocating, and tho trcadlc 15 being gradually released, the plaque is placed underneath the knil'e at the exact point where the cut. is to be made, and then by a slight pressure with the hand the work can be led so that the kuiie lei will 1 gradually pass along transversely of the line 1 to be operated on, cutting into the material [or a partial penetration. \V hon the out- Bit.

line of one recessed portion has been. travveneer to be removed can be gouged or chiseled from its place, the adhesive between the veneers giving Way to the pressure, or if the block is made 01' one piece, the wood itself is taken out by a chisel or router from between the cuts.

The operation of this machine is rapid and gives a better product than the hand cutting, and eliminates the danger of bodily injury to the operators, since there are no knives to slip from the grasp nor from the Wood. Then the plaque has been cut out, it is usually treated by the pyrographic process and the recessed portions are burned, thus saving considerable time over a process Where the burning is done to the required depth.

It will of course be understood that the knife 14 will reciprocate without turning in its bearings so that the cutting or chiseled edge is always cutting in the same plane. This stability can be accomplished by the well known use of a slot and leather or by making the shank of the knife square in a square bearing.

Having thus described my invention, what I claim is 1. A machine of the kind described comprising a support, a machine-frame mounted on the support, a knife in the machine-frame, the knife having a cutting edge on its end, mechanism within the machine-frame for rapidly reciprocating the knife, a cylinder mounted on the maehine-frame, a piston in the cylinder and engaging one end thereof, a reduced portion projecting from the lower end of the cylinder, a spring having one end abutting on the piston and havin its other ersed, the material of the upper layer of end abutting on the end of the cylinder, the

cylinder having a screw-threaded exterior, a nut on the screwthreaded exterior and engaging the under side of the machinel'rame, a tablet mounted on the top ol' the piston and underneath the knife, and a treadle connected to the lower end of the piston to operate it.

2. A machine of the kind desc ibed comprising a support, a machine-frame mounted on the support, a knife in the machine-frame,

' the knife having a cutting edge on its end,

mechanism 'ithin the machine-frame for rapidly reciprocating the knife, a cylinder mounted on the machine-frame, a piston in the cylinder and engaging one end thereof, a reduced portion projecting from the lower end of the cylinder, a spring having one end abutting on the piston and having its other end abutting on the end. of the cyiinder, the cylinder having a screw-threaded exterior, a nut on the screw-threaded exterior and engaging the under side of the machinei'rame, a lock-nut on the screw-threaded exterior of the cylinder and bearing against the first nut, a lever projecting l'rom the lock-nut for its manipulation, a tablet mounted on the top of the piston and adapted to form a work holder, and a treadle secured to the lower end of the piston for its manual manipulation.

In testimony, that I claim the foregoing, I have hereunto set my hand this 13th day HONESTUS M. ALBET of May 1 908.
